| The Feynman Lectures on Physics, Volume 2, Chapter 42-6:
| "Suppose we put a clock at the "head" of the rocket ship - that is, at
| the front end - and we put another identical clock at the "tail," as
| in fig. 42-16. Let's call the two clocks A and B. If we compare these
| two clocks when the ship is accelerating, the clock at the head seems
| to run fast relative to the one at the tail. To see that, imagine that
| the front clock emits a flash of light each second, and that you are
| sitting at the tail comparing the arival of the light flashes with the
| ticks of clock B. (...) The first flash travels the distance L1 and
| the second flash travels the shorter distance L2. It is a shorter
| distance because the ship is acelerating and has a higher speed at the
| time of the second flash. You can see, then, that if the two flashes
| were emitted from clock A one second apart, they would arrive at clock
| B with a separation somewhat less than one second, since the second
| flash doesn't spend as much time on the way."

| Einsteiniana's idiocies can destroy any rationality, even Richard
| Feynman's one!

Feynman made his bucks preaching nonsense just the same as Wheeler,
Thorne, Misner, Hawking... you name them, they can all sound good.
